a. Calculate the Force Friction
FN
The force of friction is 213.2 N
Explanation:
The frictional force acting on an object sliding on a surface is given by:
where:
is the coefficient of friction
m is the mass of the object
g is the acceleration of gravity
In this problem we have
m = 29 kg
Therefore, the force of friction is

Answer:
2
Explanation:
The mechanical advantage of the machine in the problem is 2. By definition, the mechanical advantage of a machine is equivalent to the ratio of its output force to its input force. Since it applies a force of 1000 N to an object, that is its output. Also, since a 500 N force is applied to the machine, that is its input.

Answer:
the answer is "2"
Explanation:
the answer is "2" because the formula for mechanical advantage is you divide the distance from the fulcrum, the point at which the lever pivots, to the applied force by the distance from the fulcrum to the resistance force.
